[Prior art]

 In recent years, in the heating operation by the air conditioner in the winter season, the air in the air-conditioned room is likely to be dried, and therefore, a humidifier built in the air conditioner is desired.

As a conventional humidifier, there is one disclosed in Japanese Patent Laid-Open No. 4-278134.

A conventional humidifier will be described below with reference to the drawings. FIG. 4 is a cross-sectional view of an air conditioner when incorporating a conventional humidifier.

In FIG. 4, 1 is an air conditioner body, 2 is a heat exchanger provided in an air flow passage in the air conditioner body 1, and 3 is a heat exchanger 2 provided in the air conditioner body 1. A blower for blowing 4 is a drain pan provided below the heat exchanger 2 in the air conditioner body 1, 5 is a humidifying device provided in the air conditioner body 1 on the lee side of the heat exchanger 2. The air inlet of the air conditioner body 1 is provided on the windward side of the blower 3, and the air outlet 7 is provided on the air conditioner body 1 on the leeward side of the humidifier 5.

FIG. 5 is a perspective view of a conventional humidifier. In FIG. 5, the humidifying device 5 includes a water tank 9, a humidifying element 8 having a disk shape, a part of the outer periphery of which is immersed in water in the water tank 9, and a rotary driving device 10 for rotating the humidifying element 8 in the circumferential direction. Become.

FIG. 6 is a top view of a humidifying element in a conventional humidifier. In FIG. 6, arrows indicate the flow of air flowing through the humidifying element 8.

The operation of the humidifying device configured as described above will be described below. During the humidifying / heating operation, the room air taken in by the blower 3 passes through the air suction port 6 and is warmed by the heat exchanger 2 and passes between the humidifying elements 8 of the humidifying device 5 to become warm air. The air is discharged from the air outlet 7 to the air-conditioned room.

At this time, since the humidifying element 8 is immersed in the water stored in the water tank 9, the humidifying device 5 rotates the lower part of the humidifying element 8 which is absorbed in the humidifying element 8 due to a capillary phenomenon and is sufficiently absorbed. The water is evaporated and humidified by moving to the upper part by the driving device 10 and applying warm air.

[0010]

[Problems to be solved by the device]

 However, in the configuration as described above, the amount of hot air passing through the humidification element 8 is reduced due to the air resistance of the air blower 3 of the air conditioner main body 1 due to the air resistance when the hot air passes between the humidification elements 8. As a result, the amount of water evaporated in the water tank 9 decreases, and the efficiency of the humidifying device 5 decreases. In addition, the hot air hits the tip of the humidifying element 8 to cause a peeling phenomenon, and the hot air does not uniformly contact the surface of the humidifying element 8 and the contact area with the hot air is reduced, so that the evaporation amount of water decreases and the humidifying device 5 There was a disadvantage that the ability of the

The present invention solves the conventional problems, and provides a humidifying device capable of increasing the evaporation amount of water in the humidifying element and improving the humidifying ability by bringing a large amount of warm air into contact with the surface of the humidifying element. To do.

[0012]

[Means for Solving the Problems]

 In order to achieve the above object, the humidifying device of the present invention is provided with a cut-and-raised part in a part of the humidifying element along the circumference of the humidifying element.

Further, the cross section of the humidifying element cut along a plane parallel to the rotation axis of the humidifying element has a streamlined shape.

[0014]

[Action]

 Since the humidifying device of the present invention is provided with a cut-and-raised portion in a part of the humidifying element along the circumference of the humidifying element, air blower of the air conditioner body is caused by air resistance when hot air passes between the humidifying elements. Even if the amount of hot air passing through the humidifying element decreases, the hot air comes into contact with the cut-and-raised part of the humidifying element and water evaporates at the tip of the cut-and-raised part. The capacity of the additional humidifier can be improved.

Further, since the cross section of the humidifying element cut along a plane parallel to the rotation axis of the humidifying element has a streamlined shape, the separation phenomenon is prevented from occurring when warm air hits the tip of the humidifying element. By increasing the contact area of the hot air flowing on the surface, the evaporation amount of water also increases and the performance of the humidifier can be improved.

【Example】

 Hereinafter, a first embodiment of a humidifying device according to the present invention will be described with reference to the drawings. Parts having the same configurations as those of the conventional device will be denoted by the same reference numerals, and detailed description thereof will be omitted.

FIG. 1 is a perspective view of a humidifying device according to a first embodiment of the humidifying device of the present invention. FIG. 2 is a top view of the humidifying element in the embodiment.

In FIGS. 1 and 2, reference numeral 5 ′ is a humidifying device, which is a water tank 9, a humidifying element 8 ′ having a disk shape and at least a part of the outer periphery of which is immersed in the water in the water tank 9, and the humidifying element 8 A plurality of cut-and-raised parts 12 that are cut and raised on the outer peripheral side in the rotation axis direction on a part of the humidifying element 8'along the circumference of the humidifying element 8 '. Is provided.

The operation of the humidifying device configured as described above will be described below with reference to FIGS. 1 and 2.

In FIG. 1 and FIG. 2, during the humidifying / heating operation, the air sucked from the air-conditioned room by the blower 3 of the air conditioner body 1 is warmed by the heat exchanger 2 and then the humidifying device 5 ′. The air is humidified by the humidifying element 8'and becomes warm air, which is blown into the air-conditioned room.

At this time, due to the air resistance when passing through the humidifying element 8 ′, the air volume of the blower 3 of the main body of the air conditioner 1 is reduced and the passing amount of warm air is reduced, but along the circumference of the humidifying element 8 ′. Since the cut-and-raised part 12 is provided, the evaporation of water at the tip of the cut-and-raised part 12 of the humidifying element 8'can improve the performance of the humidifying device 5 '.

Next, a second embodiment of the humidifying device according to the present invention will be described with reference to the drawings. The same components as those of the conventional device will be denoted by the same reference numerals and detailed description thereof will be omitted.

FIG. 3 is a cross-sectional view of a humidifying element of a second embodiment of the humidifying device according to the present invention.

In FIG. 3, the cross section of the humidification element 8 ″ taken along a plane parallel to the rotation axis of the humidification element 8 ″ has a streamlined shape.

The operation of the humidifying device configured as described above will be described below with reference to FIG.

In FIG. 3, during the humidifying / heating operation, the air sucked from the air-conditioned room by the blower 3 is warmed by the heat exchanger 2 and then humidified by the humidifying element 8 ″ of the humidifying device 5 ′. The air is blown into the air-conditioned room.

At this time, since the cross section of the humidifying element 8 ″ cut along a plane parallel to the rotation axis of the humidifying element 8 ″ has a streamlined shape, warm air flows along the surface of the humidifying element 8 ″. Since the amount of contact between the humidifying element 8 ″ and the warm air increases and the amount of water evaporated in the water tank 9 increases, the capacity of the humidifying device 5 ′ can be improved.

[0028]

[Effect of device]

 As described above, in the humidifying device of the present invention, the cut-and-raised portion is provided in a part of the humidifying element along the circumference of the humidifying element, and therefore, due to the air resistance when the hot air passes between the humidifying elements. Even if the air flow rate of the blower of the main body of the air conditioner is reduced and the amount of hot air passing through is small, the hot air comes into contact with the cut-and-raised part with the humidification element and water evaporates at the tip of the cut-and-raised part. Therefore, the evaporation amount of the humidifying element is increased and the efficiency of the humidifying device can be improved.

Further, since the cross section of the humidifying element cut by a plane parallel to the rotation axis of the humidifying element has a streamlined shape, the separation phenomenon is prevented from occurring when warm air hits the tip of the humidifying element. By increasing the contact area of the hot air flowing on the surface, the evaporation amount of water also increases and the performance of the humidifier can be improved.
